I plan to keep it under 6,000 rpm with a rev limiter.

This seems like a mis-match to me. Going for 76cc heads and pistons to make those work limits your ability to use any other performance head as they are all 64cc and for good reason which is chamber shape and efficiency. Even GM went to 64cc's stock after '95. If possible I'd go with 64cc heads and matching pistons to get 9.5:1.

Speaking of heads, you want to run 190cc ports with only 383cubes and a 6000rpm max? You want 180cc at best, or run the engine higher up.
